VEHICLE-WHEEL RIM.

1"0 all whom' it 'may concern.' l Be 1t known that l, JOHN M. ALDERFER, a

citizen of the United States, residing aty Sharon Center, in the county of Medinaand p so 4 lul improvements in vehicle wheel rims andv ing associated or companion rims provided State of Ohio, have invented new and useful Improvements in Vehicle Wheel Rims, of l which the following is a specification. l

This invention has relation to new and usehas especial relation to that type known as uick detachable, wherein the same is provided with at least one tire-retaining element, removable to permit lateral withdrawal ol' the tire, as contradistinguished from that type wherein it is necessary to stretch the tire over one of the lateral tire-retaining edges or anges.

The object oi' this invention, broadly speaking, is to construct a vehicle wheel rim with a seat for a tire carrying along one of its lateral edges a .tire-holding or retaining means, said retainingyjmeans adapted to cooperate with entire-retaining means on the oppositeside of the 4rim heldin position by a new and improved form of locking device.

Another object of this invention is to' so construct a wheel rim that it may be eX- panded laterally by uniting together detachablya plurality oi' members each having a seat for a tire and each provided with a tire-retaining means whereby the several inde endent members are disposed in parallel re ation circumferentially to each other.

A further object of this invention is to provide a new and im roved locking device capable of locking a etachable tire-retaining member in association with a tire and the rim on which it is mounted, and also of unit- With seats for independent parallel tires, said means in the latter instance being arranged to lock the-companion members of sai rim in coperation as well as uniting the tire-retaining means themselves to 'the rim members. Q

Other advanta es constituting objects of this invention Wi more fully appear in the subj oined description.

A practical embodiment oi this invention is illustrated in the accompanyin drawings,4 in which similar reference numera s indicate like parts in the different figures.

Vmy improved locking means for detachably I ,l securing the associated members of a wheel riln together, said retaining-means arranged 11n operative relation with respect to a run-on which is mounted a common form of tire, Y

said rim provided with outwardly-projecting side flanges. Flg. 2 1s a View oi' a modification of the rim shown 1n Fig. 1 also showing in cross section my improved locking device,

said rim larranged in operative relation with respect to that form of tire known as the clencher type, and, Fig. 3 is a view in side elevation ol my improved locking ring.

Referring to the type of rim shown in Fig. 1, the reference numeral 1 denotes a wheel felly on which is mounted an annular rim 2 the outer face oi' which constitutes a seat for 4a tire 5 and having along one oi' its lateral edges an outwardly-projectin'er iange 3 with an inclined inner face and :long its opposite edge a depending or inwardly-extending flange 4.

Arranged to coperate with the rim 2 is a second rim 6 the outer face of which constitutes a seat for a tire 7 provided along both of its side edges with de ending flanges 8 and 9 and havingarrangec circumferentially on its outer-face a projecting annular 'ridge 10 with inclined sides constituting retaining means for the inner sides of the tires 5 and 7. The tire-retaining means for the opposite side of the tire mounted on the rim 6 comprises an-endless annular member 11 having an outwardly-projecting flange 12 with an inclined inner face to receive the tire and with-a depending iiange 13 similar to the iian es 4, 8 and 9.

T e locking means for .retaining the members 2 and 6 in position as well as securing the retaining means 11 in operative relation with a tire consist of two split rings 14 and 15 each preferably provided with U-shaped outer faces in which is formed an approximately centrallydisposed circumferentialv groove 16 adapted to receive the inwardlyextending iianges of the rims and member 1.1L

These locking rings are split as at17 and are self-expansible in that they will return to theirannular shape when temporarily distorted in applying them in position.

In setting up a vehicle wheel provided l with a rim made in accordance with Fig. 1, a tire 5 is iirst mounted on the seat on the rim 2. The rim 6 is then disposed in parallel relation therewith both'laterally and circumferentially so that thexilan'ge 4 o1? the 2 is in abutting relation with the flange 9 of the rim 6. The locking ring is then sprung into position by first bending inwardly one of the ends thereof sufficiently to permit the' opposite en d to inclose the combined abutting flanges of the two lrims and afterward the balance ,of the ring is gradually forced into clamping Y. The locking ring 14 is then sprung into position to receive the combined abutting flanges 8 and 13 of the two members in the same manner as has been described with reference to the locking ring 15. To remove the tires from the rim the reverse of the foregoing operation is kcarried out.

Referring to the device shown in Fig. 2, the reference numeral 18 denotes the wheel felly on which is mounted a rim 19, the outer face of which constitutes a seat for a tire 2O and having one side edge 21 inwardly-bent forming a hook to constitute av tire-holding or retaining means andfurther provided with an inward or depending flange 22 along its opposite side edge.

Adapted to coperate with the rim 19 is a second rim 23 the outer face of which forms a seat for atire 24 and having one lat-eral edge thereof 25 inwardly-bent to constitute a tireretaining means and further provided with a depending or inwardly-extending annular flange 26.-

Mounted on the seat on the rim 23 is an annular tire-retaining member 27 having its side faces hook-shaped to constitute tire-retaining means for cooperating with the inturned lateral edges 21 and 25. The locking means for the form of rim just described consists of a split ring 2S preferably provided with a U-shaped face and a circumferentially-arranged groove 29 in its outer face adapted to receive the flanges 22 and 26 ol' the rims 19 and 23 when in abutting relation, as clearly shown in the drawings. As already described with reference to the rings 14 and 15 this ring is split and is self-expansive so as to return to its annularl formation after distortion.

In setting up a vehicle wheel provided with a rim in accordance with Fig. 2, the tire 20 is first sli ped laterally onto the seat on the rim 19 unti one of its lateral faces is in engaging relation with the inturned lateral edge 21 and a second tire 24 is then mounted on the rim shalped lateral face is in engaging relation wit i the tire 24. The-rim 23 is then disposed in lateral and `arallel relation withthe rim 19 so that the flanges 22 and 26 are in abutting relation with each other as shown in the drawings and the retaining ring 27 is in engagingrelation with the two tires 2() and 24. The ring 28 is then sprung into )osition in the manner already described wit 1 reference to the rings 14 and 15 thereby securely locking the two rims 19 and 23 in position.

From the foregoing it will be seen that a rim of substantially any width may be produced by increasing the number of the individual members and uniting them in abutting relation with each other by means of the self-expansible spring locking rings hereinbefore described.

It will be obvious from the drawings and descri tion heretofore given in connection with t e type of rim shown in Fig. 1 that the auxiliary or complementary rim 6 may be omitted and the tire-retaining member 11 positioned in cooperating relation with the tire 5 by bringing its depending or inwardlyextending flange 13 into abutting relation with the flange 4 of the rim 2 and when thus set up either of the locking rings 14 or 15 may be employed for securing the two members of the rim together.

That I claim and desire to secure by Letters Patent, is

1. The combination in a vehicle wheel, of a rim mounted thereon provided with a seat for a tire and a retaining means along one side edge thereof, said rim further provided with a depending or inwardly flange along its opposite side edger a second or complementary rim carrying a tire-retaining means along one side edge and provided with an inwardly-extending flange disposed in abutting relation with the depending flange of the first rim, and a locking element comprising an eXteriorly-circumferentiallygrooved, split, self-expansible ring adaptedto be sprung over and receive in its grooved outer surface the abutting flanges of said rims for retaining them detachably in position.
